Keep Items in tool belt... A.K.A quick slots after missions

I totally get the workshop and having a reward after completing missions and being able to purchase gear to start the next mission. However you cant keep those items and you cant repair them, not to mention the cost it takes to buy in the workshop is out of this world. We should be able to take back and reuse a select amount of items For the next mission. Enabling the quick bar or as I call it your tool belt with only 10 items to take back with you and start your next mission with would give a reason to grind more and spend more time on a mission with another reward. Other than just completing the mission as fast as you can for the workshop points.
